Souplex:So is Stinky Hikey's original personality or something? Are all of his personalities just fragments of his old personality?

That's an interresting theory. The Rooster appears to be a separate entity which is capable of knowing things which Hickey shouldn't know (eg: that leaving Frank's petrol station ASAP to avoid trouble was essential), and the Bond personality has access to safe-cracking knowledge which Hickey isn't likely to have had, unless he was a secret agent with psychic powers before, and even then it doesn't really explain Cap'n Bloodface, unless Hickey was a pirate in a previous life (the multiple personalities could just be caused by the brain scramble rather then being remnants of Hickey's personality before the scramble though). Stinky complaining about feeling cold while not wearing a sock implies that he was a new occurance, which points towards him being caused by the recent scramble.

Maybe the brainscramble went wrong and added random personalities to Hickey. Since Gladys was 'studying' humans then the aliens must have some kind of information on humans like songs, films, books etc. Maybe the process of the brainscramble was interrupted by the information gathering thing and some of the characters from Earth were passed into him?

Wow, stinky is actually a hand...So the brain scramble gave Hicky all his multiple personalities, including stinky? I always thought stinky was like Marty (or I guess that would be Steve at this point) and was some sort of living growth on Hicky's hand. Wait, didn't Stinky and Hicky sing together in one episode? O_o

Nexus Zef:I hope there is another episode with Pirate Hickey in. YARGH!

other than the tumor plot twist, this is the biggest plot twist I have seen, and one of the best starts to a season I have seen, good work. Keep it up. I thought that Gladis was just mutated, same with big worm.
